IMPROVEMENT IN PUNCHES.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, Enwnnn SenINDLur. and Cummins H. Mn'rzcnu, ofEaston, in` the county of Northampton, and State of Pennsylvania., haveinvented a. new and useful Improvement in Punches; and `we do herebydeclare that the following is a full, clear, and enact descriptionthereof, which will enable others skilled` in the art to make andusevthe same, reference being had to the accompanying drawings, formingpart of this specification.

The object el' this invention is to construct u. tool for punchingleather or any other material of a similar nature in an accurate andexpeditious manner; and the invention consists in connecting a handlever to another rockinglever, and in adjusting punches to the rockinglever in such a manner that a down pressure on the lever forces thepunches through the leather or othermnterial, as will be hereinaftermore fully described. p

Figure 1 represents a side view of the article complete, showing thedierent purtsproperly arranged. Figure 2 is a top view of the same.

Similar letters of reference indicate like parts.

A represents the bed-piece or bar of the punch; B is the plate orfoundation towliich the punch is attached, andwhich maybe of either woodor metal; C is the lever; D is another lever,\to Vwhich the punches areattached, and to which thelever Cwis connected by strap joints; E is agauge whiohis fastened in any desired position by a. set-screw; E isanother gauge, which is fastened by 'the set-screw a. These gauges areuioved towards erfrem the punches so ns to correspond with the width ofthe piece to` be punched. The upperedgles of these gauges are turned in,as seen-in fig. 1, forming flanges, the design of which is to takethe`l`eather from the punches when the punches are thrown up by thespring. G represents stnndson each side of the bur A, between which thelever C is supported; H represents two more Vstands att-ached tothebnrA, between which the lever D is supported. The lever C and the lever Dare connected together by `short straps .markedlg 'sons to form jointson each. The fulcruxn ofthe lever C is :it (Z, and the fulcrum of D isntf. c e are cars by which the bed-piece A is screwed down to the plateB. g is a. plate of brass or lead or leather, ior'of soule othersuitable material, upon which the article to be punched is laid. his n.Vgauge by which `the distance apart of the holes to be punched isgoverned. This gauge, -and also the plate g, are dovc-tailcd into -thebed-piece A., as seen at J. 7c shows the punches. These punches arefastened te the lever D. Oncol' thorn ismade fest without :i sot-screw,while the other is held by a set-screw` t', as seen in iig. 2.; Thispunch may be chng'ed to the recss m, when desired, in which position itis held by the setscrew n. Punches of different sizes maybe fitted undadjusted and fastened in the same manner. K is n. guide-screw for thclever C, to prevent its throwingthe C punches too far down. o is nspring which throws up the cud of D.

The operation of the-punch is readily understood from thedrawing.

Ilaving thus described our invention, what we claim as new, und desiretoiseeure by-Letters Patent, is-

1. Thelevers C D, connected by the straps b, the former p1ovidedwith theset-screw K, the lutter provided' with the removable punclles-cyarrnngedin relation with the longitudinal adjusting-plates E F, substantiallyns; described for the purpose specified. i

2. Ilhe adjusting-plates E F, when provided with flanges upon theirupper endsywhercby the lenther is tukcn from the punches when the latterare raised, as herein shown and described. i

3. The gauge L, when arranged in relation with the bed-plete g, wherebythe distance-apart of the holes to be punched is governed, substantiallyas 'd'escribed for the purpose specified. 4. The arrangement of theflanged adjustable guides E F, gauge It, pluto y, und punches lc,substantially as described for the purpose specific EDWARD SCHINDLER,CHARLES I-I. METZGER.
